新型防管道破裂阀在液压系统中的应用

Application of New Type Pipe Explosion-proof Valve for Hydraulic System

介绍新型防管道破裂阀的结构及其原理,并与传统的管路防爆阀比较。新型防管道破裂阀具有操作方便、易于控制等优点,能够使液压油缸在任何位置都有极好的均匀精控性。执行机构在管道破裂的条件下,可安全地由高处落向低处,保证了施工现场人员的安全。此阀在挖掘机及挖掘装载机举升工作机械中得到了广泛的应用。

The structure and principle of new type pipe explosion-proof valve were introduced, and it was compared with the tra-ditional pipe explosion-proof valve.This new type pipe explosion-proof valve is easy to operate, to control, etc.It can make the hydrau-lic cyinders have excellent uniformity of fine control in any position.Actuator can fall safely down from a high to a low position in the conditions of pipeline rupture.So this new type pipe explosion-proof valve ensures the safety of construction site personnel.The valve has been widely used in lifting machinery, such as excavators and backhoe loaders.
